Introduction to Frequency Spectrum

Radio Frequency Spectrum

Can be defined as the entire spectrum of electromagnetic frequencies used for communications; includes regulated frequencies used for radio, radar and television and ranges from about 3 KHz to about 300 GHz

The radio frequency spectrum is a limited natural resource and must be used rationally, efficiently and economically, so that countries and groups of countries may have equitable access to it. Radio waves propagate in space with no regard for political frontiers

Radio Spectrum Management

Frequency spectrum management can be defined as various administrative and technical procedures that are intended to ensure the operation of radio stations of different radio communication services at any given time without causing or receiving harmful interference. It takes place at two levels: national and international.
